Abstract
Abstract A system for collecting solar heat energy includes a plurality of shingle members arranged in shingle fashion on the roof of a stucture or building. Each shingle member is formed of a web of waterproof material which is folded and seamed to define a flat, water-containing cavity therein. Each shingle member includes a flange extending on at least two sides thereof for securing the shingle member to the sub-roof by nails or the like. At least one fluid inlet coupling and fluid outlet coupling is secured to the shingle member in flow communication with the cavity. The fluid coupling members are disposed so that the shingle members may be partially overlapped and connected in open flow communication to the superjacent and subjacent shingle members.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
143 words
A method for forming a roofing system for collecting and utilizing solar heat, using a plurality of water-proof shingle members secured to a roof deck; comprising the steps of forming a generally rectangular web of a water-proof, pliable material, securing a first fluid coupling member extending through a first portion of said web, securing a second fluid coupling member extending through a second portion of said web, folding said web at a fold line to dispose said first and second portions in overlying, adjacent relationship, forming a seam joining said first and second portions to define with said fold line a sealed chamber; arranging said shingle members in overlapping shingle matrix fashion, engaging said first and second coupling members of overlapping adjacent shingle members to connect said chambers in a fluid conducting fashion, and circulating a heat absorbing fluid through said connected chambers.
Claim 2
Independent Claim
143 words
A method for forming a roofing system for collecting and utilizing solar heat, using a plurality of water-proof shingle members secured to a roof deck; comprising the steps of forming a generally rectangular web of a water-proof, pliable material, securing a first fluid coupling member extending through a first portion of said web, securing a second fluid coupling member extending through a second portion of said web, folding said web at a fold line to dispose said first and second portions in overlying, adjacent relationship, forming a seam joining said first and second portions to define with said fold line a sealed chamber; arranging said shingle members in overlapping shingle matrix fashion, engaging said first and second coupling members of overlapping adjacent shingle members to connect said chambers in a fluid conducting fashion, and circulating a heat absorbing fluid through said connected chambers.
Claim 3
Dependent Claim
30 words
The method of claim 1, wherein the second and third steps include providing a pair of said first fluid coupling members and a pair of said second fluid coupling members.
Claim 4
Dependent Claim
31 words
The method of claim 1, further including providing a third portion of said web disposed adjacent to the upper side of said chamber and adapted to be secured to said deck.
Claim 5
Dependent Claim
36 words
The roofing system of claim 2, further including providing a fourth portion of said web disposed laterally adjacent to one side of said chamber and adapted to underlie a portion of a laterally adjacent shingle member.
